Study links gene mutation to ‘impulsive’ behaviour while drunk
People who exhibit “impulsive” behaviour while drinking alcohol are likely to carry a genetic mutation that leads them to act irresponsibly, according to a new study.
People who carry the mutation are more likely to struggle with self-controlScientists from the University of Helsinki found that people who have a mutation in the gene of the serotonin 2B receptor are more likely to become inebriated quickly, and their disposition is “noticeably different” after consuming just a small amount of alcohol.
To test the relationship of the gene and risky behaviour, scientists studied the health records of “impulsive drinkers” and their relatives.
They discovered that people who carry the mutation are more likely to struggle with self-control even when sober, but their characteristics become intensified after drinking alcohol.
The case study revealed that more than 100,000 Finns – equivalent to 2.2% of the population – were born with the mutation, as opposed to developing it in later life.
Researchers said that the findings, published in the journal Translational Psychiatry, contribute to understanding “impulse control” and could lead to an opportunity to develop new medicines.
